Autopsy report released in police shooting death of Sonya Massey

SPRINGFIELD, Ill. (WAND) - The Sangamon County Coroner's Office has released a detailed autopsy report following the police shooting death of Sonya Massey.

Massey, a 36-year-old Springfield woman, was shot and killed by former Sangamon County Sheriff's Deputy Sean Grayson in her own home after calling 911 to report a possible prowler on July 6.

Grayson has since been charged with First Degree Murder, aggravated battery with a firearm and official misconduct. He has pleaded not guilty.

In the five-page autopsy report, Coroner Jim Allmon confirmed Massey died from a gunshot wound to the head.

Toxicology results showed the presence of the anticonvulsant and nerve pain medication, Gabapentin, commonly used to treat seizures and pain caused by shingles. It's not clear why Massey was taking the medication.

She also had levels of Delta-9 Carboxy THC and Delta-9 THC in her system. Delta-9 THC is legal in Illinois.

WAND News did extensive research into Grayson's background.

On July 6, prosecutors said the shooting happened after Massey went to move a pot of hot water on the stove. They said Grayson allowed her to move the pot, and she set it on a counter. Massey told Grayson, "I rebuke you in the name of Jesus," twice, before Grayson then aggressively yelled at Massey and pulled his 9 mm pistol.

Massey then put her hands in the air, saying, “I'm sorry” and ducked for cover before Grayson fired, shooting her in the face. Grayson also discouraged the other deputy from getting his medical kit, prosecutors said. The other deputy did render aid and was the only one whose body camera was activated during the shooting.

Massey's family is expected to address the autopsy findings Friday.
